Who runs this · Why it exists · How the data works

A homeowner built this, not a tax firm.

AppealMyTax is built and run by one person: John Ives, a Houston homeowner who got tired of watching the county over-value homes and counting on people not to check. This page is who I am, why this exists, and exactly how the numbers are calculated, so you can decide for yourself whether to trust it.

Why I built it

In 2026 I protested my own Harris County property taxes. What I found out is that the data you need to win is free, public, and sitting right on the county appraisal district's own website. The catch is that it's buried in complexity, and most homeowners never realize they can pull comparable sales and challenge their assessment themselves.

The appeal firms know this. That's their whole business: they do something you could do, and they keep 25 to 50 percent of your savings every single year for it. I didn't think that was fair, so I built the tool I wished I'd had. You enter your address, it pulls real comparable properties from your county's appraisal roll, and it tells you in 30 seconds whether you're over-assessed and by how much. If you want help filing, the full protest packet is a flat $99, one time, and you keep every dollar you save.

The business, plainly

AppealMyTax is a product of RevXL LLC, a Wyoming company. No outside funding. No investors to answer to. No employees besides me. That's deliberate: it's why I can charge a flat fee instead of taking a cut of your savings, and why there's no sales team trying to upsell you.

I'm a real person and I answer my own email. If something's wrong with your packet, or you just want to ask how the math works before you pay anything, write me at john@revxl.net.

Where the numbers come from

Every figure on this site comes from public Texas county appraisal district records, the same rolls the counties use to set your tax. When the calculator says your home looks over-assessed, it's comparing your assessed value to recent sales and assessments of genuinely comparable homes in your neighborhood, adjusted for size, age, and condition.

Every comparable in your packet is a real, checkable parcel. You can look up each one on your own county's website and confirm it yourself. I don't use made-up estimates or fake testimonials, and I'd rather tell you that you're not over-assessed than sell you a packet you don't need. You can read more about that approach on the honest pricing page or see the underlying data in the press and methodology section.
